Study and analysis of contact stresses in spur gears by finite element method

Author(s):

Abstract:

A finite element simulation for surface contact stresses of gear teeth is presented. The derivation of finite element equations based on elastic large deflection. Main outlines for a finite element solution algorithm and software are given for this purpose, due to stability and measuring accuracy problems an existing finite element-package is used. In this study five positions along the contact line are considered to evaluate the contact stress on the pinion and wheel teeth. The influence of speed ratio and ratio of Young's modulus of the pinion are considered during the investigation. Found that the maximum shear stress is the beginning and the end from contact point, therefore the design life calculations of the gear tooth should be based upon these points instead of the pitch point of contact stress in the systemic design calculations. Values of the depth with shifting depended upon the position of contact point along the pressure line.
